Bio Statement

Ann Klopp is an Assistant Professor of Radiation Oncology at The University of Texas MD Anderson Cancer Center.  She is a physician-scientist specializing in the treatment of gynecologic cancers with 50% of her time devoted to laboratory research. Her laboratory research is focused on understanding effects of adipose and bone-marrow derived stem cells in gynecologic cancers.  Clinically, she is interested in the management of advanced endometrial cancers and the use of advanced radiation techniques to minimize toxicity.  In addition, Dr. Klopp has a strong interest in education and mentoring trainees in both clinical and translational research.
